I have just found this guide for that error, that actually it is a simple way to fix the problem, maybe it will be ok for you.
From the command line:
Go in the home folder and open the
.config folder (in this folder are placed the application you have installed such as skype, chrome...)
Do a simple backup of the google-chrome directory by renaming it:
mv google-chrome google-chrome-back
And try to run again chrome. It will create a nwe google-chrome directory.
If it does not works try to unistall and install again chrome.
sudo apt-get purge google-chrome sudo apt-get update sudo apt-get install google-chrome-stable
I actually got this to work by fluke. Some sights said that the problem with adding extensions to chrome browser was found on the later versions of chrome. Hence they suggested that we downgrade to chrome 34. I did that.. After that I could add the postman extension without an error, but after adding the postman app wouldn't launch at all. It wouldn't even throw an error. Just failed silently. Finally I gave up and upgraded chrome to the latest version. To my surprise I found that the postman extension that I had previously installed was now available on my list of chrome apps and I could easily launch and use it without a problem :)... So finally it was a combination = Install postman app with chrome 34 + Upgraded to chrome later version ie 46.0.2490 to launch & use app
Just handled this problem.
Uninstall current version of chrome(Mine was chrome version 46) as described by @CabaIT using purge.
sudo apt-get purge google-chrome
Install an older stable version of chrome (In my case, used google-chrome-stable- version 34.0.1847).
Install all needed chrome extensions without package installation error as there is no installation error in the older version of chrome.
Then updgrade chrome to current stable version using,
sudo apt-get --only-upgrade install google-chrome-stable
Now you will have extensions installed + an updated chrome version. Problem solved.
